The dllname specifies a DLL to delay load. You can use this option as many times as necessary to specify as many DLLs as you choose.

Home | Overview | How Do I | Linker OptionsSyntax
/DELAYLOAD:dllnameThis option causes delayed loading of DLLs. The dllname specifies a DLL to delay load. You can use this option as many times as necessary to specify as many DLLs as you choose. You must link your program with Delayimp.lib or implement your own delay-load helper function.The /DELAY option specifies.
(1)用Photoshop等制作启动画面图像，保存为bmp格式。
(2)用Appwizard建一个基于单文档的工程Splash。
(3)在资源中插入位图资源
打开VC++的资源编辑器，用鼠标右键单击Resources文件夹，选择Import命令，插入所制作的位图。如果位图超过256色，VC会弹出一个对话框，提示位图已经插入但不能在位图编辑器中显示，确定即可。将位图ID改为IDB_SPLASH。
(4)添加Splash Screen控件
①选择菜单“project”/“Add To Project”/“Conponents and Controls”打开对话框，在列表框中双击“Visual C++ Conponents”选项，选择“Splash Screen”控件，然后单击“Insert”。
②确认或修改类名和位图资源ID，单击OK确认。
③编译、连接，漂亮的启动画面就显示出来了。
(5)如果需要改变启动画面的停留时间，就修改SetTimer()函数的第二个参数，默认是750 毫秒。该函数所在位置：
int CSplashWnd::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
...
// Set a timer to destroy the splash screen.
SetTimer(1, 2000, NULL); //修改第二个参数以调整画面停留时间
return 0;
}
这样就生成了Splash1.cpp 和Splash1.h 这两个文件
2、制作基于对话框的应用程序启动画面
(1)建立基于对话框的工程Cover。 (2)文件移植
①将Splash1.cpp 和Splash1.h 两个文件从步骤一建立的工程拷贝到Cover工程中，并且分别加入到Source Files和Header Files中；
②导入位图文件到工程的资源中，改ID为IDB_SPLASH。 (3)修改代码，实现启动画面的调用
①添加CCoverApp 的InitInstance() 函数代码
#include "Splash1.h" //加在Cover.cpp文件的头文件调用部位
BOOL CCoverApp::InitInstance()
{
CCommandLineInfo cmdInfo;
ParseCommandLine(cmdInfo);
CSplashWnd::EnableSplashScreen(cmdInfo.m_bShowSplash);
...
}
②使用ClassWizard 添加OnCreate() 函数到对话框类CCoverDlg中，并修改代码#include "Splash1.h" //加在CoverDlg.cpp文件的头文件调用部位
int CCoverDlg::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
...
CSplashWnd::ShowSplashScreen(this); //显示启动画面
...
}
3、使得启动画面消失后再显示主程序
①在CCoverDlg类中添加WM_TIMER消息响应函数
void CCoverDlg::OnTimer(UINT nIDEvent)
{
// TODO: Add your message handler code here and/or call default
this->MoveWindow(300,300,600,400);
CDialog::OnTimer(nIDEvent);
}
② 在intCCoverDlg::OnCreate(LPCREATESTRUCT lpCreateStruct)中添加如下代码：
CSplashWnd::ShowSplashScreen(this);
this->MoveWindow(0,0,0,0);
this->SetTimer(1,2000,NULL);//注意这个2000一点要等于步骤1中的2000
return 0;
③在void CCoverDlg::OnPaint()的末尾添加如下代码：
this->KillTimer(1);
